'BPA-free' plastic accelerates embryonic development, disrupts reproductive system in zebrafish : science
Yeah. You know why? Because we replaced BPA with another plasticizing compound that does the exact same thing. BPS, the BPA replacement chemical, is structurally very similar to BPA and, therefore, we shouldn't be shocked when it exerts a similar impact on the reproductive system. Because we need the plasticizers to serve a particular function in the production of plastics, they are relegated to a fairly particular type of chemical structure. This means there all pretty likely to look the same and act the same. That is, as weak estrogens.

The Chemical in Cupcake Wrappers and Cookware Might Be Causing Cancer | Mother Jones
C8 is in a chemical family called PFCs (perfluorinated chemicals)—the same water- and stain-proofing class of chemicals used to make rain gear, pizza box and popcorn bag liners, stainproof upholstery treatments, and those waxy slips that hold pastries at cafes. Dozens of studies have linked PFCs to all sorts of health problems, from kidney and testicular cancer to increased risk of miscarriages. (3M phased out the chemical from production in 2002 due to potential health hazards.) [...] PFC contamination may not be isolated to the Ohio Valley. According to an Environmental Working Group (EWG) report that uses recent EPA data, C8 has been found in the drinking water in 94 counties serving more than 6 million Americans. (An interactive version of this map is available here.) [...] The EPA is in the process of investigating C8's health effects; in the meantime, it has set voluntary C8 safety standards to be used by utility companies. [...] avoid nonstick, stainproof, or waterproof items

How I discovered a coffee pot was making my patient sick - Quartz
In January, a study published in PLOS linked environmental chemical exposure with early menopause. This study suggests a connection between the ubiquitous chemicals we’re exposed to and our health. Other studies support this concept, such as a 2014 research study showing BPA in the liners of canned beverages increases blood pressure. Health care providers generally are not taught to consider common household items as a potential cause of disease, but perhaps we should be. BPA is a known endocrine disruptor. Research evidence links BPA exposure with early puberty, infertility, breast cancer, and abnormal periods. It has also been tied to obesity, prostate cancer, and neurodevelopmental problems in children. The National Health and Nutrition Survey (NHANES) found that obese adults are likely to have higher levels of BPA in their urine. [...] And lest you think “BPA-free” is the answer, the substitute plastics which contain bisphenol S or other resins appear to be equally hazardous.

BPA linked to errors in human egg development — Environmental Health News
A new study with human eggs shows that bisphenol A causes errors that can prevent eggs from developing fully and may contribute to infertility. The effects were found at the lowest dose tested, which was lower than levels that have been measured in women's ovaries. The findings are consistent with numerous animal studies.

Study links food-packaging chemical and obesity in girls
The study, published in the journal PLOS ONE, shows girls between ages 9 and 12 with high BPA levels had double the risk of being obese than girls with low BPA levels, validating previous animal and human studies, said Kimberly Gray, a health scientist at the National Institute of Environmental Health Sciences. BPA, or bisphenol-A , is a chemical laced in everything from plastic bottles to metal food containers. The chemical can alter the body's metabolism and make it harder to lose weight, experts said. [...] Because BPA easily absorbs into fatty tissue, children with obesity could also be more likely to secrete the chemical,

The anti-dopaminergic devil is in the plastic bottle: "Exposure of pregnant rhesus monkeys to relatively low levels of BPA during the final 2 months of gestation, induced abnormalities in fetal ventral mesencephalon and hippocampus. Specifically, light microscopy revealed a decrease in tyrosine hydroxylase-expressing (dopamine) neurons in the midbrain of BPA-exposed fetuses and electron microscopy identified a reduction in spine synapses in the CA1 region of hippocampus.{...] These data indicate that BPA exerts an age-dependent detrimental impact on primate brain development, at blood levels within the range measured in humans having only environmental contact with BPA."

The good news is similar effects were not observed in older monkeys.

Puberty Before Age 10 - A New ‘Normal’? - NYTimes.com
the ties between obesity and puberty start at a very young age. As Emily Walvoord of the Indiana University School of Medicine points out in her paper “The Timing of Puberty: Is It Changing? Does It Matter?” body-mass index and pubertal timing are associated at age 5, age 3, even age 9 months. This fact has shifted pediatric endocrinologists away from what used to be known as the critical-weight theory of puberty — the idea that once a girl’s body reaches a certain mass, puberty inevitably starts — to a critical-fat theory of puberty. Researchers now believe that fat tissue, not poundage, sets off a feedback loop that can cause a body to mature.

In addition, animal studies show that the exposure to some environmental chemicals can cause bodies to mature early. Of particular concern are endocrine-disrupters, like “xeno-estrogens” or estrogen mimics.

Family stress can disrupt puberty timing as well. [Evolution?]

BPA is an endocrine disruptor that interrupts hormones and, in laboratory experiments on animals, has been linked with breast cancer, prostate cancer, hyperactivity and other metabolic and behavioural problems, diseases which are all on the rise in the West. But the plastics and chemicals industries insist its use is safe and accuse campaigners of misleading the public, pointing to industry-funded studies involving large numbers of rodents that have shown no harm

8 Ways You Can Avoid Chemicals In A Can | Inspired Bites
Well, in April 2008, the National Toxicology Program raised concerns that exposure to this chemical, bisphenol A (BPA), during pregnancy and childhood could impact the developing breast and prostate, hasten puberty, and affect behavior in American children. In October 2010 in the Journal Reproductive Toxicology, another study demonstrated that in utero exposures to BPA cause precancerous prostate lesions in animals. And a Harvard School of Public Health team found elevated BPA measurements in pregnant women who eat canned vegetables daily, according to the Environmental Working Group (EWG).

Days after the 2008 study, the Canadian government decided to label BPA as “toxic.”

So while the French have banned BPA in all food packaging materials, not just in baby bottles, not just in cans of infant formula, but in packaging materials for the “grown ups,” too, the question becomes: “What in the world are we doing eating food that is marinating in this stuff?”

Tyrone Hayes + Penelope Jagessar Chaffer: The toxic baby? - YouTube
Filmmaker Penelope Jagessar Chaffer was curious about the chemicals she was exposed to while pregnant: Could they affect her unborn child? So she asked scientist Tyrone Hayes to brief her on one he studied closely: atrazine, a herbicide used on corn. (Hayes, an expert on amphibians, is a critic of atrazine, which displays a disturbing effect on frog development.) Onstage together at TEDWomen, Hayes and Chaffer tell their story.
